Datalogger

DL.OCS/N/RS485

CUSTOMER BENEFITS

• Multi-parameter probe: pressure, temperature and conductivity

• High-precision digital data logger with user-friendly software

• Thanks to the huge memory (1.5 Mio. values per channel) and the long battery lifetime (up to 10 years) the cost of ownership can be reduced to a minimum

• For varying conditions of use, 16 measuring series can be set up parallel

• Stainless steel and titanium version for use in acidic or otherwise aggressive media

FUNCTIONS

Data format Data are stored in ASCII format

Data memory Up to 1.5 Mio measurement values per channel, data remains in

memory even without battery, each measurement

value is correlated with time and date

Data transfer Read out data per measurement series, Read out all stored data, Read

out data for a defined time-period

Real-time clock Quartz-precision clock with date, Start-time of

datalogging configurable

Identification Each datalogger has a unique serial number, as well as a user-definable

description

Battery indicator Battery level indicator, calculated by considering the ambient temperature and the battery properties

Configuration Sample rate, threshold values, Identification (f.e. measuring series), Taring of measurement value,
